Windows 10: HP ProBook 450 G5 Keyboard Issue: Full Stop Key Stuck and Repeating

I’m having an issue with my HP ProBook 450 G5 laptop keyboard. The full stop . key seems to be stuck, not physically, but it keeps acting as if it’s being pressed continuously. What could be causing this, and how can I fix it?

Brightness FN keys no longer working after update to 1803 on Probook 450 G5

Hello,

After the last Windows update, among many other things, my Fn keys for brightness stopped working. I'm using a HP Probook 450 G5 and the combination Fn+F3/F4 doesn't work, so I can no longer adjust my brightness using the keyboard. I tried both with Fn lock
on and off, no luck. I have the latest drivers installed for the integrated graphics card and there's no external one. My other Fn keys seems to be working, I can adjust the volume, go into airplane mode, except the one on F8, which is for muting the built
in microphone and has been broken by Microsoft's latest update as well. They worked just fine before it installed, so I'm sure that's the cause.

Here's some additional info about the system:

I bought a ProBook 450 G6 four years ago which has been fine. You get Windows Pro, better support and claimed better build quality with the Pro version. I would remove most of the HP bloatware though.
